Definitions
- the invention relates to a drive system for a motor vehicle with an internal combustion engine and a transmission with the features of the preamble of claim 1.
- a belt drive for an internal combustion engine which has a crankshaft and a starter generator.
- the crankshaft is provided with a first pulley and the starter generator with a second pulley.
- a belt spans the two pulleys.
- a vehicle series usually has a wide range of internal combustion engines or internal combustion engines and gearboxes.
- the internal combustion engine becomes an electrical machine, in particular a starter generator assigned, different designs of starter generators are also conceivable here in order to enable a flexible design of the vehicle series.
- Belt-driven electrical machines are usually used for small-volume internal combustion engines, while integrated electrical machines are preferably used for large-volume internal combustion engines.
- An integrated electrical machine is to be understood as an electrical machine which is arranged between an internal combustion engine and a transmission.
- the electrical machine is preferably used for the start-stop operation of the motor vehicle.
- the start-stop operation leads to a saving in consumption and a reduction in the environmental impact of exhaust gases and emissions.
- the drive system according to the invention is characterized in that a power electronics unit is integrated into the drive system in a space-saving manner. This leads to a compact design and packaging advantages.
- the integrated design also leads to an improvement in electromagnetic compatibility, since only short electrical lines are required. This is particularly favorable in modern vehicles, which usually contain a large number of electrical components such as control units. Also in drive systems that have a large bell housing and which are designed for a high starting torque an embodiment according to the invention provides more installation space or volume for a power electronics unit.
- Fig. 1 is a schematic representation of a preferred embodiment
- FIG. 2 shows a longitudinal section of a section of an assembly drawing of a drive system according to the invention.
- the drive system has an internal combustion engine 1, a transmission 2 and an electrical machine 3.
- the internal combustion engine 1 is assigned a drive shaft or a crankshaft 4.
- a transmission shaft 5 is assigned to the transmission 2.
- the drive shaft 4 and the transmission shaft 5 are preferably connected to one another via a clutch 10.
- the transmission 2 can also include a converter or a torque converter.
- the transmission 2 can be operated manually or automatically. In the direction of the drive shaft 4 or the transmission shaft 5, a free installation space 6 is provided between the internal combustion engine 1 and the transmission 2.
- the electric machine 3 is assigned to the internal combustion engine 1 and is preferably operated as a starter generator.
- the electric machine 3 can also be operated as a motor and support the internal combustion engine 1, for example, when accelerating the motor vehicle (so-called boosting).
- a power electronics unit 7 is provided, which according to the invention is in the free space 6 between the internal combustion engine 1 and the transmission 2 is arranged.
- This power electronics unit 7 includes the usual components required to operate an electrical machine 3, such as converters consisting of semiconductor switches (e.g. transistors) or power semiconductors, free-wheeling diodes, additional power semiconductors, possibly a current or voltage supply source, possibly circuit breakers and electric lines. MOSFETs and / or IGBTs are preferably used as power semiconductors.
- a three-phase machine is usually used as the electrical machine 3.
- Each phase or each rotor train of the electrical machine 3 is typically controlled via power semiconductors, which are connected as a half bridge.
- the power electronics unit 7 is preferably designed such that it is at least partially ring-shaped and at least partially surrounds the drive shaft 4 and / or the transmission shaft 5.
- a housing (not shown) of the power electronics unit 7 is preferably designed accordingly.
- the electrical machine 3 is preferably drive-connected to the drive shaft 4 of the internal combustion engine 1 via a belt.
- the drive shaft 4 typically has a first pulley, not shown.
- a second pulley 9 is assigned to the electrical machine 3.
- the belt 8 spans these two pulleys. Tensioning devices (not shown) for tensioning the belt 8 can be provided.
- the electrical machine 3 is preferably positively connected to a housing 8 of the internal combustion engine 1.
- the electrical machine 3 can be arranged at a distance from the internal combustion engine 1 in the motor vehicle.
- the flexibility in the design of a vehicle series can be increased, for example, by using different electrical machines. So the volume or the size of the free installation space 6 is preferably selected such that when using an integrated electrical machine instead of a belt-driven electrical machine 3, this can be integrated into the free installation space 6 in addition to or instead of the power electronics unit 7.
- This flexible utilization of the free installation space 6 makes it possible, for example, to use different systems for realizing a start-stop operation within a vehicle series. In addition to packaging advantages, this also leads to cost advantages, since restructuring of a drive train or drive system can be avoided, which would cause high costs.
- FIG. 2 shows a longitudinal section of a section of an assembly drawing of a drive system according to the invention. Functionally identical components are provided with the same reference numerals as in FIG. 1. As already shown in FIG. 1, there is a fixed power electronics unit between the internal combustion engine 1 or its housing 8 and between the transmission 2 or its housing 9
- the drive shaft or crankshaft 4 assigned to the internal combustion engine 1 and the gear shaft 5 assigned to the transmission 2 are preferably connected by means of an intermediate flange 11 and a clutch 10.
- the power electronics unit 7 is preferably at least partially annular and preferably at least partially encloses the connection point between the drive shaft 4 and the transmission shaft 5.
- a fastening 12 is provided, which connects the power electronics unit 7 to the internal combustion engine housing
- a flywheel 13 can preferably be provided between the power electronics unit 7 and the clutch 10, which can serve to increase the uniformity of the rotational movement of the shafts or to increase the moment of inertia.
- the power electronics unit 7 preferably has a cooling unit, of which cooling channels 15 and a coolant transfer 14 are shown by way of example in FIG. 2 are.
- the cooling is preferably carried out by means of air and / or water cooling.
- an additional power storage or energy storage device (not shown), a circuit breaker (not shown) or a switching element, for example a circuit breaker, a DC / DC converter (not shown) and others, in particular electrical ones, can preferably be used in the free space 6, depending on the variant Components, e.g. a control unit or a control unit can be integrated.
- a so-called ultracap capacitor and / or an additional battery can preferably be used as the power or energy store, which can be provided in addition to the vehicle battery usually contained in the vehicle and integrated in the vehicle electrical system.
- the electrical machine 3 is designed such that it can also be operated as a generator, for example in order to convert the braking energy released when the vehicle or the internal combustion engine 1 is being braked into electrical energy.
- This electrical energy is preferably fed via a DC / DC converter into a vehicle electrical system and / or into a power or energy store (so-called recuperation).
- a second electrical machine (not shown) can be provided in the free installation space 6, which is preferably used to start the internal combustion engine 1.
- This second electrical machine is also referred to as an additional starter.
- the second electrical machine is preferably positively connected to the power electronics unit 7.
- the power semiconductors or semiconductor elements, in particular a converter, required to control this second electrical machine can be integrated in the power electronics unit.
- the second electrical machine is preferably at the point furthest radially from the drive shaft 4 or the gear shaft 5 or at the point furthest radially Most distant side of the power electronics unit 7 arranged.
